Last week the question was: What insect laid these eggs on this wheat head?
These are the eggs of an assassin bug (F: Reduviidae). There are lots of species of assassin bugs and they are excellent predators. They have piercing/sucking mouthparts which they stick into their prey and then use to suck it dry. If handled improperly, some species may “bite” people. Take a look at this page for more info.
Here is this week’s question: What is this disease growing at the base of this tomato plant?
